Heat the olive oil in a large pan over medium heat. Add in the onion, celery and carrots. Cook, stirring occasionally, until the vegetables are softened and tender (approximately 7-10 minutes).
Push the carrots and onions to one side of the pan and then add in the chicken and seasonings (coriander, cumin, salt and pepper).
Cook for approximately 4-6 minutes on each side until the chicken is slightly browned.
Add in the broth, tomatoes, jalapeño and corn.
Bring to a boil, reduce the heat and simmer for approximately 20 minutes.
Then stir in the fresh cilantro.
Serve topped with the sour cream and tortilla strips. Enjoy!
